WHEELBARROW CQNSTRUCTION.

SPECIFICATION forming part of Letters Patent No. 752,725, dated February23, 1904.

Application filed October 12, 1903. Serial N0.,176,8l2. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE GOTTFRIED TIE- MAN, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inWheelbarrow Construction, of which the following is a specification.

This invention relates to wheelbarrows; and its object is to provide astrong, rigid, and comparatively permanent construction with a minimumof weight and the fewest possible number of parts or joints.

Another object of the invention is to construct a completewheelbarrow-frame out of the staple product known as angle-irons, saidframe comprising shafts, handles, wheelbearings or journal-boxes,bed-supports, and front board-braces, all from only two angleirons; andthe invention consists in the novel manner in which said angle-irons arewrought into a wheelbarrow-frame, as aforesaid, hereinafterfullydescribed in detail, illustrated in the drawings, and incorporated inthe claims.

In the drawings, Figure 1 is a perspective view of a wheelbarrowembodying my inven- Fig. 2 is aview of one of the members of the-frame,part being broken away.

Referring to the drawings, 2 represents the side bars or shaftssupporting the bed 3. Said shafts are arranged non-parallel in the usualmanner and have their converging ends formed into journal boxes or.bearings and front braces for the board 4, while the diverging endsconstitute handles 5. Said shafts consist of ordinary angle-irons havingthe horizontal or platform-supporting wings 6 and the wings 7 at rightangles to the wings 6. Said wings are curved at the handle or divergingends into cylindrical form, as shown. The opposite ends of theangle-irons are split on the line of juncture between the wings 6 and 7,the former being bent thrice at right angles to form the front braces 8and the latter partly shortened and its end bent upon itself, formingthe journal-bearing 9. A space is preferably left between the oppositeparts of the loop thus formed andeoncentric holes 10 bored through saidloop.

Only one of these holes is shown in Fig. 2,

the location of the other hole being obvious from the foregoingdescription. The loop or bearing portion 9 may have only its inner sidedrilled for the axle or spindle 11, leaving the outer side imperfora teto serve as an end bearing for the axle llof the wheel 12. j 13represents a pair of legs, which may be formed out of sheet metal andbolted or riveted to the wings 7. If desired, the shafts themselves mayalso be made to serve as legs by forming them into loops correspondingto the outlines of the legs shown herein.

1 1 represents the bed of the barrow, secured to the wings 6 by means ofscrews, bolts, or rivets 15 through holes 16. (Shown by dotted lines inFig. 2.) The shafts adjacent to the handle portions are bent twice insubstantially opposite directions, as shown at 17 and 17 The braces 8form an abutment for the end board 4, and said braces are secured attheir ends by means of apertured inturned bends, one of which is clearlyshown 1n Fig. 2,. for WlllCll registering apertures are made in theupper wings '6, and each of said braces is fastened by means of a bolt19 or other suitable means. I

When the front board is bolted to the abutment formed by the braces 8and the bed 3 likewise bolted or fastened to the shafts, a very steadywheelbarrow is the result without joints liable to work loose. This isnotably true of the spindle-bearings, which usually consist of separateparts, especially in wheelbarrows made from metal and including thebraces 8, shafts, and handles all in one or two pieces of metal.

In the construction shown herein the whole frame consists of only twoangle-irons, and that part of the wheelbarrow material which comprisesthe greatest area of structural materialnamely, the bed-may be made outof such light material as wood without sacrifice in the main idea of arigid structure with the fewest possible joints. great strength, anexceedingly light wheelbar row is the result.

It is obvious that modifications may be made in my construction withoutdeparting from the spirit of the invention, which I do not wish toconfine to the specific form herein shown and described.

Hence, considering its Having thus described my invention, I claim asnew and desire to secure by Letters Patent 1. A wheelbarrow-frameconsisting of a pair of two-web angle-irons supporting the wheel andconstituting the bed-frame, each of said angle-irons being formed at oneend respectively into a substantially rectangular abutment whichincludes braces therefor and also including wheel-bearings and the otherend being formed into a substantially tubular handle.

2. A wheelbarrow-frame consisting of two angle-irons curved at one endtransversely into tubular handles and having their opposite ends split,one of said split portions being bent into a front-board abutment andfastened upon the body of the angle-iron, and the other of each of saidsplit portions being bent upon itself and apertured for thewheel-spindle.

3. A Wheelbarrow-frame consisting of apair of angle-irons, part of oneweb of each of said irons being formed into an integral bearing for thewheel and part of the other web being formed into a three-sided abutmentfor the front board with the extreme end thereof fastened upon anotherportion of said web; the opposite end of each of said angle-irons havingboth of its Webs curved toward each other into the form of a handle, andsuitable legs for said frame.

4:; A wheelbarrow consisting of two integral angle-irons each thereofhaving one end of its Wings curved into tubular form and having itsopposite end split at the juncture of the wings into two straps with oneof the latter bent four times at substantially right angles and theother bent or folded upon itself and apertured for the wheel-spindle.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.

GEORGE GOTTFRIED TIEMAN.
